Your typical jQuery object will contain references to any number of DOM elements, and that's why jQuery objects are often referred to as collections. If you want to do any manipulating with specific elements (e.g. getting a data attribute, calculating specific positions) then you need to use .each()...
You may want to do this if the remote repository is migrated. The command for changing the remote url is:
git remote set-url
It takes 2 arguments: an existing remote name (origin, upstream) and the url.
Check your current remote url:
git remote -v
origin https://bitbucket.com/develop/myrep...
Let's say we have a problem of size n. Now for each step of our algorithm(which we need write), our original problem becomes half of its previous size(n/2).
So at each step, our problem becomes half.
StepProblem1n/22n/43n/84n/16
When the problem space is reduced(i.e solved completely), it cannot ...
A higher-order function, as opposed to a first-order function, can have one of three forms:
One or more of its parameters is a function, and it returns some value.
It returns a function, but none of its parameters is a function.
Both of the above: One or more of its parameters is a fu...
If we have a c++ project that uses a config.h configuration file with some custom paths or variables, we can generate it using CMake and a generic file config.h.in.
The config.h.in can be part of a git repository, while the generated file config.h will never be added, as it is generated from the cu...
If you have a cmake module . You can create a folder called in to store all config files.
For example,you have a project called FOO, you can create a FOO_config.h.in file like:
//===================================================================================
// CMake configuration file, base...

Comparator cmp = [ compare:{ a, b -> a <=> b } ] as Comparator
def col = [ 'aa', 'aa', 'nn', '00' ]
SortedSet sorted = new TreeSet( cmp )
sorted.addAll col
assert '[00, aa, nn]' == sorted.toString()
Here is a very simple example of a function that "promises to proceed when a given time elapses". It does that by creating a new Deferred object, that is resolved later and returning the Deferred's promise:
function waitPromise(milliseconds){
// Create a new Deferred object using th...
Correlated (also known as Synchronized or Coordinated) Subqueries are nested queries that make references to the current row of their outer query:
SELECT EmployeeId
FROM Employee AS eOuter
WHERE Salary > (
SELECT AVG(Salary)
FROM Employee eInner
WHERE eInner.Dep...
my @letters = ( 'a' .. 'z' ); # English ascii-bet
print $letters[ rand @letters ] for 1 .. 5; # prints 5 letters at random
How it works
rand EXPR expects a scalar value, so @letters is evaluated in scalar context
An array in scalar context returns the number of elements it ...
The series of events here is supposed to work as follows:
Compile code with -pg option
Link code with -pg option
Run program
Program generates gmon.out file
Run gprof program
To add profiling flags, you must add to your CMakeLists.txt:
SET(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -pg"...
Inheritance among models can be done in two ways:
a common abstract class (see the "Model mixins" example)
a common model with multiple tables
The multi tables inheritance will create one table for the common fields and one per child model example:
from django.db import models
c...
// An 8-bit 'byte' value:
byte aByte = (byte)0b00100001;
// A 16-bit 'short' value:
short aShort = (short)0b1010000101000101;
// Some 32-bit 'int' values:
int anInt1 = 0b10100001010001011010000101000101;
int anInt2 = 0b101;
int anInt3 = 0B101; // The B can be upper or lower case.

The example reads the first line from a file. It uses an instance of BufferedReader to read data from the file. BufferedReader is a resource that must be closed after the program is finished with it:
static String readFirstLineFromFile(String path) throws IOException {
try (BufferedReader br = n...
The following example shows other ways you can use the underscore in numeric literals:
long creditCardNumber = 1234_5678_9012_3456L;
long socialSecurityNumber = 999_99_9999L;
float pi = 3.14_15F;
long hexBytes = 0xFF_EC_DE_5E;
long hexWords = 0xCAFE_BABE;
long maxLong = 0x7fff_ffff_ffff_ffffL;...
